title: An efficient heteropolyacid catalyzed acylation of pyruvate esters to alpha-acyloxyacrylate esters as potential candidate monomers for bio-based polymers.
abstract: Alpha-acyloxyacrylate esters were efficiently synthesized from pyruvate esters and carboxylic anhydrides under mild conditions. These esters are potential candidate monomers for bio-based polymers with high durability and transparency. Tungsten-based Keggin type heteropolyacids, especially H(3)PW(12)O(40), worked more effectively as catalysts for this reaction than other typical acids.
